The current 4runner hasnt changed drastically since like 2002. The current generation has been in production since 2009. Those things are absolute tanks when maintained regularly. I dont see them going away anytime soon with so many having been produced over 14 years. Last model is likely going to be 2025 once the 6th gen is announced.

California, previous dealer messed up on a lot of repairs.

For the most part, if the part that is “leaking” isnt actively dripping, i dont recommend to reseal/replace it. I kinda go by the idea that if i personally wouldnt do it, then i wont recommend you to do it.

Ive replaced ecu’s for funky stuff on tacos, camrys, and tundras. Wouldnt be surprised this was your issue.

If your alternator was good, battery was good, and the rack itself is good, there isnt much else to look for besides the ecu.

They make us take pictures at work. Incorporate pictures into our bonus too. Sucks that shady dealers give the good ones a bad name.
